How to Fix FUSE errors on MacOS

If your cloud drive does not mount properly on MacOS and gives you an error similar to the following image, the most likely reason is the Mac OS increased security protocols that were introduced with Catalina (10.15). This article also applies to Mojave (10.14) and High Sierra (10.13).

First, make sure the Mac Client is the highest version that is available for your CentreStack. Mac Client is included in CentreStack installation. May need to upgrade CentreStack to the latest release, to get latest Mac client.

The proper way to get the Mac Client that is designed for your CentreStack is to sign in on the web portal, then access the downloads page from the user menu on the top-right of the screen.

If you are getting the error right after the installation of the Mac Client, the FUSE error may go away after a reboot of the computer. Simply reboot the Mac and try to open the Cloud Drive again.

If rebooting doesn't solve the issue, then you should check the System Preferences->Security & Privacy on your Mac. Under the Privacy tab, make sure that anything labeled with the words "Cloud Drive", "Gladinet", and/or "FUSE" are allowed to run without restrictions. FUSE (Filesystem in Userspace) is an open-source software interface that extends the file handling capabilities of the Mac OS, with support for NTFS and many other file systems. The CentreStack Mac Client relies on FUSE to mount the cloud drive among other things.

Some users have also reported FUSE errors while using a Mac through a remote session. This happens because remote session software emulates mouse-clicks/keyboard interactions, and the Mac OS blocks such emulated user-interactions. You need to make sure that the word "Allow" appears next to any items relating to emulation software gestures and remote sessions in the System Preferences->Security & Privacy on your Mac. The names of these entries will vary depending on the software that you are using to do your remote sessions.

Finally, if the FUSE errors persist, please follow the steps below to troubleshoot and collect debugging information. Email us the information along with full-screen screenshots of any errors to ticket@gladinet.com to open a support ticket.

Open the Applications/Utilities/Terminal application and type the following commands:

whoami
(this will let you see the username of the logged in user)

sw_vers
(this will show you the operating system's name, version, and build number)

uname -a
(this will show you the operating system's kernel version)

lsvfs
(this will show you a table of supported file system types)

df -a
(this will show you a table of mounted file systems) 

id
(this will show you the IDs of the local users and groups, as well as ports used by various services)

kextstat | grep osxfuse
(this will show you if OSX Fuse is loaded)

. if after issuing the kextstat command you don't see any output

ls /Library/Filesystems/osxcore.fs/Contents/Extensions/

the command lists all folders under Extensions. If you see a folder matching your MacOS version (such as 11.0), run

sudo kextload /Library/Filesystems/osxcore.fs/Contents/Extensions/11.0/osxcore.kext

. if after issuing the kextstat command you see an output that contains "com.gladinet.osxfuse.filesystems.osxgluefs (3.8.0)"

sudo sysctl vfs.generic.osxcore.tunables.admin_group

sudo kextunload -b com.gladinet.osxfuse.filesystems.osxgluefs

After this set of commands, the problem should be fixed. If, howerver, OSX Fuse is still not working, please do the following.

On the Terminal window where you ran the commands above, hit Command+a and then Command+c on your keyboard. Open a Simpletext document and hit Command+v. Save the document as terminal.txt to your desktop.

Now open the Application/Utilities/Console. From the Console's Action menu, enable "Include Info Messages" and "include Debug Messages".

Debugging information will also appear in the Console/system.log. Please apply a filter for "osxfuse" on the top-right portion of the Console app. Once you can see the hour and minute when the first entry occurs, change the filter to a timestamp (example: "10:03"). The final, filtered system.log will contain the system activity for the minute when the OSX Fuse mounting occurred. Copy the text into a Simpletext document and save it to your desktop as systemlog.txt.

Send an email to ticket@gladinet.com with a descriptive subject/body and the following attachments that resulted from the steps above:
